To all whom 'it concern:

Be it known that I, LINooLNf A. THORNBURG, of Hartford City, Blackford county, Indiana, have invented a new and useful Glass Melting and Drawing Apparatus, of which the fpllowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in

which- I Figure 1 is a vertical section of apparatus constructedin accordance with my invention; Fig. 2 is a section on the line II'II of 1; and Fig. 3 is a diagram plan view showing one form in whichthe apparatus can be arranged in relation to the furnace and drawing machines.

My invention provides means by which molten glass can be drawn directly from a melting tank into a pot and thence drawn in the form of sheets, cylinders, etc. It results in an important saving in labor and in cost of manufacture, and has other important advantages which will be appreciated by those skilled in the art.

The drawings show the preferred embodiment of my flaring chamber 6, towards and from the outlet on'a horifurnace, and 13, 13, are tracks on which they can be moved from the furnace to the stations 14, where the glass isdra'wnfrom the pot by the machines.

15 indicates the melting-out stations on the return end of the track 12. While on the trackatstation 15 the kilns are brought into communication with suitable gas b'urners 16, by which heat is applied to the kiln through openings 8" in the sides thereof, and the residual glass is melted from the potivhich is inverted for that purpose. The kilns carrying the pots are thence moved successively to the furnace, the stopper-block 5 is opened to permit-the molten glass to flow into the pot, and the kiln with the pot is then moved ito the drawing station at which there is also a burner or burners 16 to apply heat to the bottom of the pot. When 4 the glass has been drawn from the pot the kiln is moved back to the stations 15 and the operation is repeated.

It is.

a kiln or fur- The tracks 13 are provided with suitable switches, so that a kiln with a pot thereon can be run from the furnace to any one of the drawing stations, and thence back to the furnace by way of the melting stations. 4 is a burner for melting chilled glass from the outlet 3 and spout 4.

The use of the stopper-blocks renders the molten glass easy to control and overcomes the .difliculties which have heretofore prevented the tapping of molten glass from furnaces.

I claim:

1: Apparatus for drawing glass, comprising a melting I furnace having a'discharge outlet, a movable not adapted "to receive molten glass therefrom, and :i'drawing station;

substantially as described. 1

-2. Apparatus for drawing glass, comprisi iga melting f'urnace having a discharge outlet, 'a movable not adapted' to receive molten glass therefrom, a melting-out station, and a drawing station; substantially as described.

3. Apparatus for drawing glass, comprising a melting furnace having a discharge outlet, a movable pot adapted to receive molten glass therefrom, a meltingout station, a drawing station, and a movable kiln by which the pot is carried; substantially as described.

i 4. Apparatus for drawing glass, comprising a melting furnace having a discharge outlet, a movable not adapted to receive molten glass therefrom, a melting-out station, a drawing station, and a' movable kiln by, whlchthe poi: is carried, the not being reversible; substantially as described. i

l 5. Apparatus for melting and discharging molten glass,

comprising a furnace provided with a glass outlet, and a horizontally movable stopper for the outlet situated be nected to such extension; substantially as described. 1

. 7. Apparatus for drawing glass, comprising a melting furnace having a discharge outlet, "a movable pot adapted to receive molten glass theretrbm, a plurality of drawing stations, and a system of tracks leading from the furnace -to the drawing stations and back to-the furnace; substantially as described.
